文摘
- •
Bulk ceramics with superlattice structure were prepared by a normal sintering method.
- •
Glass-like thermal behavior with a low thermal conductivity of ∼2 W/(m·K) was shown.
- •
Nb doping enhanced the electrical properties of the insulating (Nd0.55Li0.36)TiO3.
- •
A ZT value of 0.05 was achieved at 650 K in the 5 at%Nb-doped (Nd0.55Li0.36)TiO3.
